Increased risk of type 2 diabetes is experienced by women – but not men – who work more than 45 hours a week, according to a new Canadian scientific study. The risk is not increased for those who work from 30 to 40 hours. It is estimated that some 439 million people will be living with diabetes by 2030, nearly 50% more than in 2010. In 2015, diabetes costs 1.31 trillion dollars in the world economy.
Researchers, led by Dr. Maui Gilbert-Wime of Quebec’s FRQS Research Center and the Toronto Institute of Labor and Health, who published the publication in the British medical journal BMJ Diabetes Research & Care, analyzed data for 7,065 workers aged 35 up to 74 years at a depth of 12 years.
For the survey, employees were divided into four groups according to their working hours per week: 15-34, 35-40, 41-44 and over 45 hours. During the study, about one out of ten people developed diabetes, mainly men, older and obese.
It was found that the longer duration of the work week was not associated with an increased risk of type 2 diabetes in men, even the likelihood of diabetes declined, the longer a man worked.
On the other hand, for women who worked more than 45 hours per week, the risk was significantly increased (63% on average) than those who worked 35 to 40 hours.
The difference observed between the two sexes has no obvious explanation, according to the researchers. One possibility is that women actually work even more when household chores and family responsibilities are taken into account, which can cause chronic stress in their bodies, thereby increasing the risk of hormonal disturbances and body resistance in insulin.
